Problem with javac signalling errors in files other than currently scanned

[vkazanov]

Flymake gives "Configuration error" and switches off if errors are only found in other files than a given one. I.e., it fails when I check my java project with javac, and current file has no errors at all, but one of the dependencies is flawed.

The following hack fixes the problem:

(defadvice flymake-post-syntax-check (before flymake-force-check-was-interrupted)
    (setq flymake-check-was-interrupted t))
(ad-activate 'flymake-post-syntax-check)

I have debugged the "flymake-post-syntax-check" function and found out that it does not normally work with the case. It's either the checking process has a zero exit code or no errors in the current file, or a non-zero exit code and errors in the file. I do not fully understand the meaning of the third case - the one that the hack uses.

Anyway, in my case - non-zero exit code and no errors in the file checked - flymake fails.

PS I am okay with giving more code-related details.
